Case 33-2008

A 63-year-old woman was admitted to the hospital because of a 3-week history of dyspnea on exertion, associated left subscapular burning pain, and a mild dry cough. She had a history of ulcerative colitis, which was most recently treated with azathioprine and infliximab. On examination, there were inspiratory wheezes and rales, without expiratory wheezes. Chest imaging showed ground-glass opacities in both lower lobes. A diagnostic procedure was performed.
